The settled science informs us that the more often you flip a coin, the more likely it is that there will be a 50/50 split of heads to tails. In other words, if you flip a coin 20 times, the probability of achieving a ratio of 8 heads and 12 tails diminishes greatly if you flip it 40 or 60 times. The closer you get to 100 coin flips, the closer you will get to a perfect 50/50 split of heads to tails.
